US stocks' losses widened, with the Nasdaq 100 down more than 1%.

According to TradingBeats monitoring, Hyperliquid’s Shanghai-listed Korean stock mapping contract SKHX fell approximately 10.46% since 00:00 today, currently trading at $938.71, while its US-listed ADR mapping contract SKHY dropped around 7.80% over the same period, with a 2.66 percentage point gap in declines. Based on the conversion ratio, SKHY’s implied premium relative to SKHX has expanded from roughly 42.89% at 00:00 today to 47.14%, a rise of about 4.25 percentage points, with the premium itself increasing by around 9.9%. Over the same period, SKHX fell 10.46% while SKHY dropped 7.80%, and the latter’s relative resilience further widened the price gap between the two contracts. Against the backdrop of the price divergence between the two regions, a whale trader who shorted the Korean stock and went long on the US ADR has reaped substantial profits. The account currently holds: - SKHX short position: $17.59 million, average price of $1,293.84, with an unrealized profit of approximately $6.6549 million; - SKHY long position: $6.59 million, average price of $175.04, with an unrealized loss of around $1.7636 million. After netting the two legs, the unrealized net profit is roughly $4.8913 million. This account is not a fully hedged spread trade. Converted based on the number of underlying shares, its ADR long position only covers about 25.5% of the Korean stock short position, leaving a large net short exposure overall. A large portion of the current profit still comes from SKHX’s sharp decline. It is reported that the whale also added approximately $356,100 to its SKHX short position today, while reducing its SKHY long position by around $1.3973 million, further increasing the directional short bias of the portfolio. After including another DRAM short position with an unrealized profit of about $315,100, the net unrealized profit of the account’s three positions totals approximately $5.2063 million.

According to TradingBeats monitoring, SKHX on Hyperliquid has dropped nearly 15% in the past 24 hours, currently trading at $939.46, down roughly 12.88% from its level when last night’s CPI data was released. Amid the sharp plunge, large long positions have been liquidated one after another, incurring losses. Since last night to this morning, three verified whales have closed a total of approximately $3.881 million worth of SKHX long positions, with combined losses of around $887,000 via both stop-loss orders and forced liquidations. One whale liquidated roughly $1.493 million in long positions, taking a loss of about $347,000 (address: 0xcb13); another long trader reduced positions via voluntary loss, but their remaining positions were eventually forced liquidated, with total losses of around $261,000 in this round (address: 0x5fc2). The third whale’s approximately $1.008 million in long positions was also liquidated in batches, adding another loss of roughly $279,000 (address: 0x3b5b). All three accounts currently hold no SKHX positions. However, after the plunge pushed funding rates into negative territory, bargain-hunting funds have since flowed back. SKHX’s hourly funding rate reversed rapidly: from -0.08399% at 08:00 to +0.03080% at 09:00, and further rising to +0.03550% at 10:00, flipping the long-short pricing dynamic for the contract. Long liquidation risks remain unresolved. Liquidation distribution data shows that around $5.09 million in potential long liquidation exposure is clustered near the $888 level for SKHX, roughly 5.5% below the current price. If the price continues to drop, this area will be a key watch point for the next round of leveraged long positions being forced out.

Vitalik Buterin posted on social media to congratulate the Airbender team, stating that the speed race has come to a complete end, and the top priority for zkEVMs should fully shift to security. He noted that this requires formal verification of the following: the equivalence between arithmeticization and Ethereum specifications, a hard upper limit on the ratio of proof cost to block gas limit, and proof of the system’s own security.
